Central Banks

If you've ever asked yourself why your loan interest rate shifts, or why the prices at your supermarket keep either going up or down, or why currencies all of a sudden either gain or lose value, a lot of the time it can be traced back to powerful, yet largely invisible, institutions called central banks. They are arguably the most powerful institutions within a country's financial system and deeply influence a nation's economy, from the Money in your pocket to the world economy, usually without you even noticing.

Many people are often unaware of what central banks do or how they impact daily life. This guide will remove the smoke and mirrors and reveal how these economic giants operate, why their decisions are important, and what their decisions mean for your financial future.

What Is A Central Bank?

A central bank is a country's leading financial authority. It is not a commercial bank where you open an account or put your paycheck. Instead, it is in charge of issuing the nation's currency, controlling the amount of Money available to the economy, and ensuring the stability of the banking sector.

Some providers include the Federal Reserve Bank (Fed) in the United States, the European Central Bank (ECB) in the Eurozone, the Bank of England in the United Kingdom, and the Bank of Japan. Even though each has a different structure, they generally exist to achieve three broad purposes:

1. To sustain price stability – controlling inflation.

2. Promoting economic growth – providing the environment to help foster jobs and investment.

  1. Ensuring financial stability – preventing banking crises.

A Short History of Central Banking

Central banking is not new. The first central bank was the Bank of Sweden (Sveriges Riksbank), established in 1668! Over the years, countries recognized the necessity of a single point of control for the nation's money supply and the "lender of last resort" function for their economies to avoid financial panics.

The modern central bank refined its function much more considerably after the Great Depression of the 1930s to accommodate the wishes of governments for stronger control over national economic conditions. Since then, central banks have had an increasingly robust management role in inflation, interest rates, and, at times, global financial crises like the financial meltdown in 2008 and the COVID-19 economic emergency.

Central Bank Major Functions

Central banks may appear complex, but they are supported by primary functions that can be communicated in simple themes.

1. Controlling Inflation and Prices

Inflation is defined as prices rising over an extended period. A little inflation is expected and can be healthy for an economy. Too much inflation destroys purchasing power. Central banks can control inflation through interest rate adjustments, raising interest rates to slow or cool the economy, or lowering interest rates to stimulate spending and investments.

2. Issuing Money

Most central banks have the sole authority to issue a nation's Money. If you hold an actual bank note, you will find the name of the central bank on it, typically guaranteeing its monetary value.

3. Regulating the Money Supply

Central banks can regulate the level of Money in circulation throughout the economy by performing actions that include open market operations, buying or selling government bonds.

4. Lender of Last Resort

Central banks can provide banks with emergency funds if they experience a sudden loss in liquidity and need funds to stay afloat, avoiding a banking collapse.

5. Regulation of the Financial System

Central banks often regulate commercial banks and require that the banks adhere to regulations on capital requirements, lending standards and risk limits.

How Central Banks Impact the Economy

The primary tool utilized by most central banks is called monetary policy and is typically separated into two main components:

1. Expansionary Policy - Overall, lowers interest rates and increases the money supply to stimulate economic growth.

2. Contractionary Policy - Generally, interest rates and money supply are increased to try to limit inflation. For example, suppose the economy is in a state of high unemployment. In that case, the central bank may assess lowering interest rates so that it is cheaper for businesses to access borrowed Money. Hence, they spend Money on equipment or other capital expenditures. Conversely, if the economy is in an overheating inflationary state, they may take action by raising interest rates to incentivize saving and to decrease spending.

Interest Rates

Interest rates can be thought of as the thermostat of the room. When the room is too cold (low economic activity), lowering interest rates turns up the heat and ultimately makes borrowing cheaper. When the room is tooChanges in interest rates impact:

• Mortgages - Lower interest rates mean cheaper home loans.

• Business loans - Companies can afford to borrow more.

• Consumer spending - Borrowing and credit are cheaper, so people may be inclined to spend more.

• Currency - Higher interest rates attract foreign investment, which typically increases the value of the currency.

Central Banks in Times of Crisis

When economies experience unexpected shocks, the central bank can help stabilize the marketplace.

• 2008 Financial Crisis:  The U.S. Federal Reserve lowered interest rates and purchased large amounts of government bonds to inject open market liquidity into the system.

• COVID-19 Pandemic: Central banks across the world dropped rates, purchased Money, and coordinated with governments to prevent their economies from collapsing during lockdowns.

These decisions are sometimes controversial due to the large amounts of Money involved and their impact on income inequality. However, they are not intended to create economic and financial instability; instead, they aim to prevent economic growth from falling into a depressing recession.

Central Banks in Times of Crisis

Independence vs. Government Influence

One of the most discussed areas in central banking is the independence of central banks from political influence. The operational independence of central banks has been applied in numerous countries to grant independence, which allows a central bank to make decisions based on the economic conditions facing the economy, rather than political pressure.

However, they typically collaborate closely with governments in times of crises. Finding the right level of independence is a tightrope act. If too much autonomy is granted, central banks can feel unaccountable. However, if too little is given, they may become political bodies making short-term political decisions. This can ultimately harm economic performance. Criticism of Central Banks

Not everyone believes central banks are entirely beneficial; there are several critics' voices arguing:

• Their policies can grow the gap between the rich and the poor.

• Low interest rates can spur overly risky borrowing.

• They may sometimes fail to thwart financial bubbles.

• If they print too much Money, they may inadvertently spur inflation over the horizon.

Despite their critics, most economists believe modern economies would be far less stable without them.

The Global Network of Central Banks

Central banks do not operate in a vacuum. They often collude and coordinate with one another through organizations like the Bank for International Settlements (BIS) and more formal collaboratives that share information on trends and strategies to fortify global financial stability. Admittedly relatively new, the interconnected world produces financial phenomena where changes made at the U.S. Federal Reserve can cause ripples through emerging markets in a matter of hours.

Why You Should Care about Central Banks

Central banks make decisions every day that immediately and ultimately affect our lives, even those of us who don't walk through the front doors of central banks:

• The rate on your mortgage or car loan;

• The price of your retirement savings in your retirement plan;

• The price you pay for imported goods;

• The value of the currency you bring with you to the bar or cafe abroad;

Ultimately, understanding central banks can help you make better financial decisions, improve your ability to anticipate market trends, and even uncover connections between various economic headlines.

Conclusion

Central banks operate in the background, but their impact is everywhere. Central banks are the quiet builders of economic stability by creating favourable conditions with tools such as interest rates, the money supply, and acting as regulators to guide nations through either quiet waters or stormy seas.

So the next time you hear about an interest rate shift, or a leading market indicator, and think you understand the situation, know that there is much more to the story than meets the eye; at the same time, behind the scene, a central bank is likely making moves that impact not only the economy, but effectively your financial climate.
